2. Contents • Performance of discovery procedure • References • This documents presents simulation results for PAC operating in synchronous mode (DCN:15-13-390-01-008[2]) Soojung Jung et al. (ETRI)

3. Performance of discovery procedure • Terms and concepts • Status of a PD • Tx status: a PD is transmitting own discovery signals using a selected discovery Resource Unit(RU) • Rx status: a PD is receiving other PD’s discovery signal through discovery RUs except own (/selected) discovery RU • At a specific time (/on a discovery RU), a active PD is either Tx status or Rx status Soojung Jung et al. (ETRI)

4. Performance of discovery procedure • Terms and concepts(cont.) • average number of discovered PDs • Average of numbers of PDs which is discovered by a PD • “to discover” latency • Interval between the time that a PD is turned on(/activated) and the time that a PD(in the Rx status) discovers successfully other PD (in the Tx status ) Soojung Jung et al. (ETRI)

5. Performance of discovery procedure • PD deployment • Number of Total RUs=1024 • Uniform random drop in 500m*500m • Number of PDs =[100,500,1000,1500,2000] • Number of Total RUs=64 • Uniform random drop in 125m*125m • Number of PDs=[100, 200, 300,400,500] • All PDs are sequentially activated from time 0. After activation, a PD starts to select a discovery RU for transmission of own discovery signal and listens other PD’s signals Soojung Jung et al. (ETRI)

6. Performance of discovery procedure • Simulation configuration Soojung Jung et al. (ETRI)

7. Performance of discovery procedure • Performance Metrics • Average number of discovered PDs • Ratio of discovered PDs • The ratio between the number of successfully discovered PDs and total PDs • CDF of “ to discovery” latency Soojung Jung et al. (ETRI)

8. Performance of discovery procedure • Average number of discovered PDs 7 UFs Num.of RUs <Num.of PDs 3 UFs *SAL: select after listening Soojung Jung et al. (ETRI)

9. Performance of discovery procedure • Average number of discovered PDs(cont.) Num.of RUs >Num.of PDs Num.of RUs <Num.of PDs Soojung Jung et al. (ETRI)

10. Performance of discovery procedure • Ratio of discovered PDs Over 90% Num.of RUs <Num.of PDs Soojung Jung et al. (ETRI)

11. Performance of discovery procedure • Ratio of discovered PDs(cont.) Num.of RUs >Num.of PDs Num.of RUs <Num.of PDs Soojung Jung et al. (ETRI)

12. Performance of discovery procedure • CDF of latency 3~7 UFs Num.of RUs <Num.of PDs Soojung Jung et al. (ETRI)

13. Performance of discovery procedure • CDF of latency(cont.) Num.of RUs >Num.of PDs Num.of RUs <Num.of PDs Soojung Jung et al. (ETRI)
